Specification of Letters Patent.

Patented Mar. 5, 1912.

Application filed .Tune 13, 1910. Serial No. 566,644.

To all ech-0m t may concern Be it known that I, ROBERT COOKE SAYER, a subject of the King of Great Britain and Ireland, residing at Clyde Road, Redland, Bristol, England, have invented certain new and useful Improvements in Aerostatics, of which the following is a specification.

The object ofthe present invention is to lighten bodies by a central vacuum retained by a periphery formed of adjacent continuous chambered or tube cells containing fluid pressure.

The invention essent-ially consists of a hollow body of any form, and material, a. peripheral external skin inside and a series or group of cells in contact with the skin and one another; the hollow body is exhausted so as to form a vacuum Within it lighter than atmospheric air, and atmospheric air or a very light gas is compressed into the cells of the periphery to resist the compressive effect of the vacuum and eX- ternal fluid by its tightening the skin down to the cells, the cells against one another, and their sides against their contained compressed iiuid, and thereby maintain the form of the body; the cells are arranged in lengths which may or may not be connected by valves; hollow passages or chambers may connect the peripheral sides, or ends of the body, to let adjacent external fluid and its pressure pass through them and by the vacuum act in tension upon their intrados or walls, which may be regulated by doors or valves.

The invention is disclosed by the accompanying drawing wherein-- d Figure 1 represents a typical spherel in elevation; Fig. 2 is a sect-ion on the line A-A Fig. 1; Fig. 3 is a developed section on the line B-B Fig. 2; Fig. 4 is an elevation of a tubular body with strut passages; Fig. 5 is a sectional plan on the line C-C Fig. 4; Fig. 6 is a section on the line D-D Fig. 5; Fig. 7 is an enlarged section in art the same as Fig. 6.,`

gata/Z description-Referring now particularly to the drawing a Figs. 1, 2, 3 shows typically the invention adapted for a sphere; Figs. 4 to 7 showing the same adapted for atube or ellipse having hollow passages o connecting its sides and ends, through which'may pass external adjacent fluid in which the body a may be iioating, to act against and put their Walls or sides in tension and enable them to act as struts to the pe1"iphery,with or without valves or doors b2.

The bodies c may be of any material, have a hollow interior c, a peripheral. exterior skin rl, inside which, Figs. l to 3. are arranged chambered cells e of any form, a few, or all, being connected, if desired, through their walls e2 at es, and in part formed by the skin al; or alternatively Figs. 4 to 7 the periphery is formed by straight, or spiral, Zig-zag, transverse, or (as shown) longitudinal tubular cells e in many lengt-hs which may or may not be connect-ed by valves; or in one lengt-h arranged for' their walls e2 to normally touch one another at e3. The tubular cells have occasional apertures e4 between them, formed by spacing meinbers, or rings e'5 on the tubes e, enabling the vacuum and external fluid to act on the skin d at e5, as well as on the tubes e which may vary in diameter to form the curved ends a2 (Fig. 4), or elliptical or other shaped bodies a, so as to taper at the ends or from their center, and maintain Contact with each other and the skin d; or the tubes may be of uniform diameter and be flattened towa-rd their ends a2 for the sam-e.

The bodies a may be long and straight, or curved tubes with closed ends, or with their ends connected to form a ring; and in all cases form the whole, or a part only of any shaped body, to lighten or strengthen it, give it flotation or upholding by acting as ribs, or otherwise; the essential featurebeing a vacuum to lighten the body a for the external liuid to compress together the parts of a cellular periphery containing fluid pressure of the lightest nature, adapte-d to maintain the form of the body a.

I claim- 1. A body for aerial navigation having a central vacuum, and having a series of adjacently disposed chambers or cells arranged along its outer periphery, each of said -chambers or cells containing a'gas under pressure.

2. A body for aerial navigation having a central vacuum, and having a series of adjacently dispo-sed chambers or cells arranged along its outer periphery, each of said chambers or cells containing a gas under pressure, and valve openings arranged so as to afford communication between adjacent cells.

3. A body for aerial navigation having a series of adjacently disposed chambers or cells arranged along its outer periphery, each of saidr chambers or cells containing a gas under pressure, a passageway tl'irough said body to admit external fiuid, and said body being formed with a vacuum in the space between said passageway and said chambers or cells.

4. A body for aerial navigation 11a-ving a series of adjacently disposed chambers or cells arranged along its outer periphery, each of said chambers or cells containing a gas under pressure, a passageway from end to end of said body for admitting exten nal Huid, laterally arranged passageways passing across said first-named passageway, and 'said body being. formed with a vacuum in the space between said passagcways and said chambers or cells.

A body for aerial navigation having a series of adjaeently disposed longitudinal tubular chambers arranged alo-ng its outer periphery, each of said chambers containing a gas under pressure, and a chamber surrounded by said tubular chambers having a vacuum therein.

6. A body for aerial navigation having a central vacuum, and having a series of adjacently disposed longitudinal tubular chambers arranged along its outer periphery, each of said chambers containing a gas under pressure, a portion of said tubular chambers contacting with each other, and a portion being spaced apart from each other.

7. A body for aerial navigation having a series of adjacently disposed longitudinal Itubular chambers arranged along its outer periphery, each of said chambers containing a gas under pressure, a port-ion of said chainbers contacting laterally with each other while a portion are spaced apart a suit-able distance, a passageway ext-ending from end to end of said body to admit external fluid,

and said body being formed wit-h a vacuum in the space between said passageway and said tubular chambers.

In testimony whereof I have affixed my signature, in presence of two witnesses.

ROBERT COOKE SAYER.
